ROBERT mumumrmnnxor BELLEFoNjrE, PENNSYLVANIA.. f

` KNUCKLE.

To all 'whom may concern.'

'a citizen of the United States, residing at Bellefonte, in the county of Center and yao State of' Pennsylvania, have invented certainnew and useful Improvements in Knuckles; and I do hereby declare the following to be a full,l clear, and exact description of the invention, such as will enable others skilled-in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in knuckles, andmore particularly to the self-lubricating class to be,

used in connection with the steering mechanism of automobiles or the like, rockerv arms for engines, bearings for transm1s-` sion `of power, and being especially useful in the many clevis or knuckle bea-rings for harvesting machinery, shaft or tongue clips for horse-drawn vehicles, high gradehinges, universal joints in power transmission, agricultural implements, etc.,

An object of this invention is Ito improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eilicient inuse, readily operated, and providing against lost motion incident to the wearing of any of the parts.

With the above and other objects in view, this invention resides in the novel features f construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Figure 1 is a perspective v1ew of my improved knuckle; Fig. 2 is a vertical sectional view thereof; and Fig. 3 is a detail perspective view of one of the bearing conesv with its locking pin removed.

Referring to the drawing by characters of reference, the numeral 1 designates generally aV clevis, consisting of` an internally threaded rod-receiving socket 2, upon the forward end of which are formed overlying arms 3, provided with centrally disposed alining circular apertures 4, formed at one side thereof with offset semi-circular keyengaging recesses 5, which extend the entire length of the said apertures 4. l

A centermember A6 is held between the terminals of the arms 3, andhas formed thereon an extension 7. This extension 7 is provided at one side thereof with an enlarged head 8 having locatedtherein aver- {Specication of Letters Patent. Patented Mar, 16, 19115, Application mea April 11', isn. serial No. 62o,444.

g tically disposed opening 9, provided with Beit known that I, ROBERT F. HUNTER,

outwardly flared conical-shaped ends 10, adapted to receive the tapered inner eX- tremities 11 of upper and lower bearing cones 12 and 12, which are held againstv rotation within the circular apertures 4 by conical-shaped or pointedlocking pins 13 seated within the before-,mentioned semicircular recesses 5, and similar conicalshaped recesses 14 formed in the sides of the cones N12. These recesses i14'terminate atpoints substantially intermediate the length of the cones, and always hold the upper ends of the pins 13 slightly above the edges-of the said cones, whereby they will at all times-be forced downwardly through the recesses 5 and 14 by the head 15 and locking nut 16 located at the oppositeends of' a connectingbolt 17 ,which .extends throughl the,

y engagingv rcones12 and 12 operate to securelylock said bearing cones in the openings 4 in the arms 3 by increasing the' diameter of the bearing' surface on a line extending through the centers of said pins 13 and through the centers of the cones 12 and 12.`

' The bearing cone 12 is slidableupon the -bolt 17, while the bearing cone 12 is threaded thereon, which permits the adjustment of said cones 12 and 12.

It will be noted that the opening 9 is considerably larger-than the opening 18, which permits of the inward adjustment of the cones 12 and 12 in case they become worn,

by the rotation of the bolt 17 ,which serves to force thecones 12 and 12` inwardly by their threaded sliding engagement with the said bolt, in which position the cones may nut 16, which locks the bolt against rotation.

The space 9 between the bolt 17, cones 12 and 12 and inner periphery of the center member 6 may be filled with grease or the like, whichfobviously may be fed to all parts of the knuckle upon movement of the center member.

The previous disclosures illustrated one embodiment of my invention, but it is to be understood that minor changes inthe debe securely held against displacement by the ef ooilstiuotion, formations? eoxzifzdzfiee1 tions and ermifigemeiits of 'the Various' parte may be veseited te Within the scope of the, eplpeiided `Gleim Without seerioing ed- Ventsges ei the invention.,
